Thank You for the replies. I'm so happy, some guy actually bought one. This (link) is my first real engineering project and I actually made one that looks nice enough for someone to buy. My first one, that I was brave enough to sell online, even though, hot glue was used.
As for user ave1, I can just simply make few for you, but it could take some time. I do not need to earn on these, but as I told before, I'm not a professional, and problem is not with the electronics, logic or program but with these darn boxes. I literally buy some china product (this), rip all innards out, and put my stuff in, just because I need this darn shell, that does not come empty anywhere. Ans shipping to me from China is ~month. And even then, cable hole is too big so I put hot glue in it. In shorter words, this works great, but mechanically.... there is how to improve. If it is ok with you, I can make and send one or few to you. Let me know, if interested. Right now I'm working on DS4->genesis/vectrex. I'm close, but darn boxes The hell is in the shell&shipping not on breadboard.
